Abstract
BackgroundTo evaluate whether the addition of a probiotic could improve Helicobacter pylori (H.P.) eradication rates and reduce the side effects of treatment in children.MethodsBetween July 2008 and July 2011 all patients with a clinical, laboratory and endoscopic diagnosis of H.P. positive gastritis referred to our Unit were included in the study. Patients suffering from allergy to any of drugs used in the study, with previous attempts to eradicate H.P. and those who received antibiotics, PPIs or probiotics within 4 weeks were excluded from the present study. Patients were randomized into two therapy regimens (group A and B): both groups received standard triple treatment (omeprazole, amoxicillin and clarithromycin) while only group B patients were also given a probiotic (Probinul - Cadigroup). Patients compliance was evaluated at the end of the treatment. Successful eradication was defined as a negative 13 C-urea breath test (C13-ubt) result four weeks after therapy discontinuation.ResultsA total of 68 histopathologically proven H.P.-infection children (32 male and 36 females) were included in the study. All of the patients in both groups used more than 90% of the therapies and no patients were lost at follow up. All side effects were selflimiting and disappeared once the therapy was terminated. Epigastric pain was observed in 6 (17.6%) group A vs 2 (5.8%) group B patients (P<0.05), nausea in 3 (8.8%) group A vs 1 (2.9%) group B patients (P<0.05); vomiting and diarrhea were observed in 2(5.8%) and 8 (23.5%) group A patients, respectively and never in group B (P<0.05). There was no significant difference between the two groups in terms of constipation (5.8% in group A and B). Four weeks after the completion of therapy, 56/68 patients (82.3%) tested negative for H.P. on C13-ubt. H.P. was eradicated in 26 patients (76.4%) in group A and in 30 patients (88.2%) in group B. There was no significantly difference in the rate of H.P. eradication between group A and group B (p=0.1), although the success rate for H.P. eradication was higher in group B than in group A.ConclusionThe addition of a probiotic formula to triple therapy significantly decreased the frequency of epigastric pain, nausea, vomiting and diarrhea.
Highlights
To evaluate whether the addition of a probiotic could improve Helicobacter pylori (H.P.) eradication rates and reduce the side effects of treatment in children
Besides treatment studies on children are limited by the small number of infected children in each individual center [14,15,16], this study aimed to evaluate whether the addition of a commercially multi-strain probiotics to a 7 days triple therapy in children could improve H.P. eradication rates and reduce the side effects of treatment
The patients were randomized into group A and group B for H.P. eradication
Summary
To evaluate whether the addition of a probiotic could improve Helicobacter pylori (H.P.) eradication rates and reduce the side effects of treatment in children. According to the Maastricht III consensus report, H.P. eradication is recommended for patients with gastroduodenal ulcer disease, atrophic gastritis, MALT lymphoma, first degree relatives of patients with gastric cancer, patients with unexplained iron deficiency anemia and chronic idiopathic thrombocytopenic purpura In both developed and developing countries, H.P. infection is most frequently acquired during childhood, and it is associated with family size, familial clustering, low socioeconomic status and education. As for adults, “infanti” treatment will fail in approximately 10-35% of patients, and H.P. infection will remain resulting from several factors, including nonadherence to therapy related to adverse effects or complicated dosing regimens and increasing antibiotic resistance [3,4,5]. Besides treatment studies on children are limited by the small number of infected children in each individual center [14,15,16], this study aimed to evaluate whether the addition of a commercially multi-strain probiotics to a 7 days triple therapy in children could improve H.P. eradication rates and reduce the side effects of treatment
